[0027] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] In the description of this application, it should be noted that for directional words, such as the terms "center", "horizontal", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and so on, the directions and positional relationships indicated are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of this application.

[0029] It should be noted that the terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0030] The terms "comprises" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0031] One of the preferred embodiments of this application is as follows: Figures 1 to 7 As shown, a new crosshead copper driver for a die-casting machine includes a copper driver body 1 and a bearing band 2. The copper driver body 1 can be fixedly mounted with external parts, and the bearing band 2 is limitedly mounted on the inner wall of the copper driver body 1.

[0032] It should be noted that the crosshead of a die-casting machine serves as a guide, ensuring stable performance under high-pressure and high-frequency operating conditions, thereby ensuring a smooth die-casting process and the quality of die-cast parts. Conventional crossheads are complex to install, costly to design, and inconvenient to secure. Furthermore, traditional crossheads are not wear-resistant, and after prolonged use, they cannot guarantee accurate guidance during use, resulting in a short service life.

[0033] Therefore, in this embodiment, a bearing band 2 is provided on the copper driver body 1. The copper driver body 1 is provided with a mounting groove 12, and the bearing band 2 is installed in the mounting groove 12. When the copper driver body 1 is working, the bearing band 2 is the first part to rub against external parts. The bearing band 2 can reduce the wear of the crosshead copper driver, thereby increasing its service life. After a certain number of years of use, the bearing band 2 can be replaced first and then the copper driver body 1, thereby saving usage costs.

[0034] In this embodiment, the conventional crosshead copper driver requires a pressure plate for securement. This conventional fixing method not only increases the overall design cost but also makes the installation and replacement of the crosshead copper driver extremely cumbersome and inconvenient for the operator. Furthermore, if the conventional crosshead copper driver requires a pressure plate during installation, the seal between the conventional crosshead copper driver and the external components cannot be guaranteed.

[0035] Therefore, in this embodiment, Figure 4 、 5 As shown, a flange 10 is provided at one end of the copper main body 1. Specifically, a flange 10 is provided on the outer wall of one end of the copper main body 1 along the circumferential direction of the copper main body 1, and the diameter of the flange 10 is larger than the diameter of the copper main body 1. At the same time, a plurality of connecting holes 100 are provided on the flange 10, and there are multiple connecting holes 100, which are evenly spaced along the circumferential direction of the flange 10. The copper main body 1 is threadedly connected to the external parts through the multiple connecting holes 100, so that the connection method between the copper main body 1 and the external parts is simple and stable, and the sealing of the connection between the copper main body 1 and the external parts can also be well ensured.

[0036] In this embodiment, the traditional copper main body 1 needs to rub against external parts during operation, resulting in the need for frequent replacement of the copper main body 1 during long-term use. Otherwise, the copper main body 1 that has been used for a long time cannot be used normally after wear, thereby affecting the use of the entire die-casting machine.

[0037] It is understandable that the traditional copper body 1 needs to be replaced after long-term use. However, the replacement process of the copper body 1 is very troublesome, and long-term and frequent replacement increases the workload of the staff and also increases its technical cost.

[0038] Therefore, in this embodiment, Figure 2 、 3As shown, the present application installs a bearing band 2 on the copper body 1. When the copper body 1 is in operation, the bearing band 2 first rubs against the copper body 1, followed by the copper body 1. Therefore, after long-term use, the bearing band 2 can be replaced first, followed by the copper body 1. This arrangement reduces the workload of staff and reduces technical costs.

[0039] It should be noted that due to the requirements of the working scene, the bearing belt 2 cannot be installed on the outer wall of the copper body 1, so the bearing belt 2 is installed on the inner wall of the copper body 1. However, the copper body 1 needs to be sleeved with external parts and then threaded, so the bearing belt 2 cannot be directly installed on the surface of the inner wall of the copper body 1.

[0040] Therefore, in this embodiment, Figure 2 、 3 As shown, a mounting groove 12 is provided on the inner wall of the copper body 1. The mounting groove 12 is annular. If the bearing belt 2 is installed in the mounting groove 12, the inner wall of the copper body 1 remains flat and smooth without protrusions. This arrangement ensures that even if the bearing belt 2 is provided on the inner wall of the copper body 1, the copper body 1 can still be normally connected to external parts and threaded.

[0041] In this embodiment, since the copper main body 1 requires friction during operation, and since the copper main body 1 is sleeved onto an external part, both the inner and outer walls of the copper main body 1 require friction. As can be seen from the above, the inner wall of the copper main body 1 is provided with a bearing band 2, but due to its installation method, the outer wall of the copper main body 1 cannot be provided with the bearing band 2. However, the upper part of the traditional crosshead copper main body is relatively weak, and will also wear out after long-term operation, resulting in the need to replace the entire copper main body 1. Therefore, even if the copper main body 1 is provided with a bearing band 2 on the inner wall, its service life still has a lot of room for improvement.

[0042] It is understandable that due to the installation method of the copper body 1, the outer wall of the copper body 1 cannot be increased in thickness independently. Therefore, the outer wall thickness of the copper body 1 can only be changed by changing the center position of the inner hole and the outer circle of the copper body 1.

[0043] Therefore, in this embodiment, along the axial horizontal installation direction of the copper main body 1, the center positions of the inner hole and the outer circle of the copper main body 1 are changed so that the installation upper wall of the copper main body 1 is thicker than the outer wall of the traditional crosshead copper main body, thereby making the copper main body 1 of the present application more wear-resistant during long-term use, and further making the guidance accuracy of the copper main body 1 more precise during use.

[0044] It can also be understood that the present application changes the center position of the inner hole and outer wall of the copper body 1 to change the thickness of the upper wall and lower wall of the copper body 1. Therefore, if Figure 6 As shown, in the installation direction of the copper main body 1, the center of the inner hole of the copper main body 1 is eccentric downward relative to the center of the outer circle of the copper main body 1.

[0045] It should be noted that the thickness of both the upper and lower walls of the copper body 1 is extremely important when the copper body 1 is in operation. Therefore, the thickness of the lower wall should not be ignored simply because the upper wall thickness is required. The thickness of the upper and lower walls need to be in relative proportion. Considering the working environment of the copper body 1 during operation, in this embodiment, the minimum thickness of the lower wall of the copper body 1 is limited to 90% to 95% of the maximum thickness of the upper wall of the copper body 1.

[0046] It should also be noted that, as can be seen from the above, in this embodiment, the minimum thickness of the lower wall of the copper body 1 is defined as 90% to 95% of the maximum thickness of the upper wall of the copper body. However, the thicknesses of the upper and lower walls of the copper body certainly each have their own optimal thickness settings. Therefore, in this embodiment, the optimal thickness of the upper wall of the copper body is defined as x, and the optimal thickness of the lower wall of the copper body is defined as y. In this embodiment, x is equal to 10.2 mm, and y is equal to 9.6 mm. Furthermore, the thickness settings of x and y are merely optimal thickness settings.

[0047] In this embodiment, Figure 5 As shown, in order to ensure the normal operation of the copper main body 1, an annular oil groove 11 is provided on the outer wall and the inner wall of the copper main body 1, and an oil inlet hole 110 is provided at the position of the oil groove 11 relative to the upper wall of the copper main body 1.

[0048] The above describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments. The above-described embodiments and the specification merely illustrate the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. These changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
